Anxiety is a natural response that triggers the release of hormones like adrenaline, making the body more alert and ready to deal with danger. This 'fight or flight' response protects against physical threats and releases other hormones once danger is over. However, it also reacts similarly to other stressful situations, such as opening the mail, speaking in public, moving, losing a job, or attending a party.
